These inputs are normally wired to VCC, GND, or left unconnected (actual threshold voltages vary as a percentage of VCC). Internal termination resistors hold the unconnected inputs at VCC/2. If these inputs are switched, the function and timing of the outputs may glitch and the PLL may require an additional tLOCK time before all data sheet limits are achieved. 5. This is for non-three level inputs.

This is for non-three level inputs. 9. Both outputs of pair must be terminated, even if only one is being used. 10. Each package must be properly decoupled. 11. AC parameters are measured at 1.5 V, unless otherwise indicated. 12. Test Load CL= 25 pF, terminated to VCC/2 with 50up to185 MHz and 10 pF load to 200 MHz. 13. Tested initially and after any design or process changes that affect these parameters. 14. TTB is the window between the earliest and the latest output clocks with respect to the input reference clock across variations in output frequency, supply voltage, operating temperature, input clock edge rate, and process. The measurements are taken with the AC test load specified and include output-output skew, cycle-cycle jitter, and dynamic phase error. TTB is equal to or smaller than the maximum specified value at a given output frequency. 15. SKEW is defined as the time between the earliest and the latest output transition among all outputs for which the same phase delay has been selected when all outputs are loaded with 25 pF and properly terminated up to 185 MHz. At 200 MHz the max load is 10 pF. 16. Guaranteed by statistical correlation. Tested initially and after any design or process changes that affects these parameters. 17. Rise and fall times are measured between 2.0 V and 0.8 V. 18. fNOM must be within the frequency range defined by the same FS state. 19. tPWH is measured at 2.0 V. tPWL is measured at 0.8 V. 20. fNOM must be within the frequency range defined by the same FS state.
